Cydia: Cannot Locate Package (server overload?)

I'm getting a message on all packages I try to install that says "Cannot Locate Package." I just did the Absinthe 2.0 JB for 5.1.1 and everything went fine. I refreshed Cydia manually and still can't get it. If I add a non-default source, it finds packages within that just fine.

Are the Cydia source servers just overloaded right now? Is there something I need to fix? THANKS!

I notice a lot of errors, but slowly things have been coming back. Try closing the Cydia app completely, then refreshing under packages.Also, when you try to download an app, it will initially come back with an error. Just try it again and it will work properly. Must be a bug or overload for sure.
